For $200CAD I got the whole thing from a scrap yard. It is in excellent shape (compared to mine) and even the wheel bearing looked new. The brake disk and the holding screw came off it without a hitch, I swapped my strut insert and coil spring, used the better thrust bearing and it went on the car asap. New brake disk and pads went on, I made sure to use copper grease on the biding faces. The car runs great, no more vibrations or noises and I did an alignment already (had to put winters on anyway). I took the old hub and stuck disk to work, where we tried using all kinds of presses, a torch and a hammer chisel. The disk is not coming off the hub. So me and my 4lb hammer and a wood block were going nowhere... In the long run, I think I made the right decision. 200,000 km and running great! Thanks all for help, Ben
